I had to convert the pants of these guys, and I’ll freely admit they are a shoddy job, but they should work on the table.
Ironically, for what was meant to be a shoddy job of converting, and a fairly slap dash paint job, on a real throwaway unit, I actually like these guys a lot.
What does that say about me?
Aaany way here's the solo shots, with a bit of info about each conversion.

Sarge. in the codex, really does have a Hellgun like the troopers, and not upgrading him to a power weapon or anything keeps the disposable melta delivery system a bit cheaper.
He was a standard trooper till his head came off. replaces with an empire militia head, and a cadian respirator, with GS work to bring it all together.

Just a vanilla trooper this one. I did intend to replicate a Kasrkin camo in desert colours, but the base tan just looked really good to me, so I left it unmolested. never underestimate the power of a complimentary colour scheme :)

Vanilla trooper two. I spent a bit more time on their faces than the rest of them, knowing those well sculpted masks would be a draw. glad I did, but the rest of them have such glaring faux pas, mould lines, bits of bad paint, ah well. maybe next time I’ll take some care, I do have five more of these somewhere.

Melta trooper one, formerly hellgun trooper 3, I chopped it off and swapped in a melta, yes it’s ugly, but it’ll do and it satisfies WYSIWYG


This is melta trooper two, formerly flamer trooper one. this one took a bit more doing, involving some press moulded melta bits and the front of a melta gun. it’s ugly too. but looks more like the Kasrkin melta trooper.
Well that's another unit done, you know I might actually reach a point where I can call this IG army “finished” and move on to my Orks or Wolves.
Now that’d be scary.
